I need some advice on how i can plant my flowers in the pond. I recently bought some flowers for my pond to help the fish to have some shade from the sun, and some oxygen plants as well. I have no idea how i should plant them as my pond is very deep approximately 1 meter deep and the plants are quite small. I know the Lillie's can float on top but what about other plants like Myosotis palustris Pond Marginal Water Plant and Mares Tail Pond Oxygenating Water Plant?
